In packeting machines, more particularly for packing cigarettes or thelike rod-like articles, it is already known, for transferring a numberof articles to be packeted from a conveyer band moving forwardcontinuously to another conveyer band running parallel thereto, toemploy a pusher or ram, the operative face of which lies parallel to theconveyer band, and which in its movement towards the articlesparticipates at the same time in the longitudinal movement of theconveyer band in the longitudinal direction of the said band. In a knownconstruction of a device of this type, the ram or pusher is actuated bymeans of two cranks or eccentrics or the like.

In this case, however, difficulties arise when the machines run at aparticularly high speed, because the complicated type of driving meansdoes not always work with thorough accuracy, due to the possibility ofplay being set up, and consequently such driving means is onlyapplicable for slow-running machines.

The object of the present invention is to provide a device, in which,due to the simplest possible construction and the improvement of themeans for driving and guiding the ram, any play ispracticallyimpossible, and satisfactory and accurate working is ensured. For thispurpose, according to the invention, the pusher is reciprocated in aguide inclined to the conveyer band, so that the said pusher can bedriven by a single eccentric, cam or the like.

A construction of the invention is shown by way of example in theaccompanying drawing, wherein: I

Figure 1 is a plan of the construction,

Figure 2 is an elevation and Figure 3 is a diagrammatic illustration ofa part of the device on a larger scale.

Referring to the drawing, a is a conveyer band on which the articles tobe packeted, for example cigarettes, are fed. As shown by Figure 3, theband is preferably provided with trough-like depressions a in which thearticles to be packeted, that is to say the cigarettes, are situated.The band is moved forward continuously by a device not shown in thedrawing, and the cigarettes or the like, lying in the troughs a are tobe transferred to an adjacent, stepwise moving band. As shown in Figure3, this latter band I) is also provided with troughs b for the receptionof the individual cigarettes, the'said troughs b being preferably flaredfunnel-fashion at the receiving end in order to facilitate theintroduction of. the cigarettes. In Figure 3, a cigarette Z is shown inits position on the conveyer band b. The

transfer of the cigarettes from the one band to the other band iseffected by means of a pusher 'c, which (Figures 2 and 3) is preferablyconstructed in the form of a comb on the side facing the band a, that isto say, it is. provided with 5 two guide bars 1 and f fixed to themachine 5 frame. The direction of the guide bars I and f is inclined tothe conveying direction of the two conveyer bands a and b. Consequently,when the cross-head c with the bell crank lever d and d slides in thedirection towards the conveyer band a, the bar c makes an obliquemovement, namely, in the first place a movement transversely to theconveyer band a, by which movement it pushes the cigarettes 01!? theconveyer hand a and onto the conveyer band b, and simultaneouslya'movement with the conveyer band, this latter movement being necessary,because the conveyer band a, of course, is moving continuously. Ofcourse, the transfer to the conveyer band b is effected at the instantat which the conveyer band b is moving in the same direction and at thesame speed as the conveyer band a. Thecrosshead e is driven by means ofa lever g, which is pivoted at o to the machine frame and carries aroller 0', running in a groove ina camdisch. .'1heleverg is connected tothe cross-heads by an arm i. The end of the arm i engages the forked endof the iever'gby means of a pin.

0n the same spindle as the cam disc it there is mounted another cam disck, on which runs the roler m of a double lever 11;. rotatable about aspindle m". The other end of the said double lever is pivoted to a yoken. In addition, there isprovided a link 0 one end of which likewiseengages the yoke n, while the other end of the said link 0 is pivoted tothe machine frame. The lever m and the link 0 constitute a parallelguide. Consequently, when the roller m runs on the cam disc 7:, the yoken will be raised and lowered. The yoke 11 has secured to it a guide 11on which the roller d runs. The cam discs h and k are driven off theshaft (1 of the machine by means of a pair of bevel gears r, 1' Thedevice accordingly functions as follows: While the two bands 11 and bare running at the same speed and in the same direction, that is towardthe right in Fig. 1, the cross-head e is moved by the lever g along theguides and f and consequently the bar c makes the oblique movementhaving components in the transverse direction and in the longitudinaldirection of the conveyer band a, that is to say, it transfers thecigarettes to the band b, and at the same time, due to the inclinedposition of the guides f, I, it participates in the longitudinalmovement of the conveyer band a. During this time, the guide bar .17. isstationary, since the roller m is running on the cylindrical part of thecam disc k. At the end of the forward movement, the roller m runs on toa rise on the cam disc k, consequently the yoke n with the guide p islowered, the result of which is that the roller d running along theguide p is pressed downwardly and rotates the lever 11 and d with thepusher c in a counterclockwise direction in Figure 2, so that the pusherc is raised. This raising is necessary in order that theconveyer band acan move further continuously during the return of the pusher into itsinitial position. After the raising of the pusher c, the return movementof the cross-head .e is eifected by means of the lever 9. At the sametime, the pusher c moves over the band a back into its initial position,and at the end of its return movement, it is again lowered upon the band(1, because the roller m then runs oil the higher cylindrical part ofthe cam disc k. Consequently, the yoke n is again raised and the deviceis again in its initial position. Accordingly, the cam disc k isprovided with two cylin-' dn'cal parts k and k which engage the roller mduring the forward and return movement of the cross-head, and withrising and falling parts connecting the two parts 10 and k Of course,other mechanisms may be employed for carrying out the various movements.For example it is also possible to employ an intermittently actuatedrack gear for the upward and downward movement of the yoke, and aneccentric mechanism or the like may be employed instead of the cammechanism for the forward movement of the cross-head.

I claim:-

1. A device for efiecting the transfer of a number of articles to bepacketed, as cigarettes or the like, from a conveyer band moving forwardcontinuously to a conveyer band running parallel thereto, comprising, incombination with the conveyer bands, a pusher, the operative face ofwhich lies parallel to the conveyer bands, a cross-head, on which saidpusher is pivotally mounted, a guide inclined to the conveyer bands onwhich said cross-head is reciprocated to move the pusher obliquely ofthe bands, means for reciprocating said cross-head, and meansco-opcrating with said pusher at the end points of the reciprocatingmovement and adapted to turn it upwardly or downwardly.

2. A device according to claim 1, in which the last mentioned meanscomprises a guide engaged by said pusher and along which the pusher runsand a mechanism adapted to move said guide upwardly and downwardlythereby turning 'the pusher at the end points of the reciprocatingmovement upwardly or downwardly.
